TY - JOUR AB - The lattice parameters, cell volume, and structure of a sample of phase pure triclinic tricalcium silicate were determined using in situ, high-temperature synchrotron powder diffraction and full-profile Rietveld refinement. The temperature range covered was from ambient to 740°C. Evidence of superstructure was found. The T2 type structure with disordered SiO4 tetrahedra was observed, and an average structure for the subcell (P1?, a = 11.7416(2) Å, b = 14.2785(2) Å, c = 13.7732(2) Å, ? = 105.129(1 °, ? = 94.415(1)°, and ? = 89.889(1)°) is presented. Differential thermal analysis and X-ray fluorescence was also performed.
